Additional Features
Windowing
A fully configurable window can be selected for readout.
The parameters to configure this window are:
x_start. The sensor reads out 24 pixels in one single clock cycle.
The granularity of configuring the X start position is also 24.
Every value written to the windowX_2 register must be multiplied
by 24 to find the corresponding column in the pixel array.
x_kernels. The number of columns that is read out
(x_kernels*24 in full frame mode) in subsampling mode
x_kernels*48 represents the number of columns over which
subsampling is done. The x_kernels value must be written to the
windowX_4 register.
y_start. The starting line of the readout window, granularity of 1.
Note that in subsample mode, the correct y_start position must
be uploaded (exact value depends on color or B/W subsampling
mode). This value must be written to the windowX_1 and
windowx_2 register.

y_end. The end line of the readout window, granularity of 1. In
all cases (even in reverse scan), y_end are larger than y_start.
Note that in subsample mode, the correct y_end position must
be uploaded (exact value depends on color or B/W subsampling
mode). This value must be written to the windowX_3 and
windowX_4 register.
In case of windowing, the effective readout time is smaller than
in full frame mode, because only the relevant part of the image
array is accessed. As a result, it is possible to achieve higher
frame rates.
Subsampling
Subsampling reduces resolution while maintaining the constant
field of view and an increased frame rate. LUPA1300-2 supports
monochrome and color subsampling modes of operation. The
pixel order for one complete row is shown in
